William Fausser commented on PDFBOX-1188:
-----------------------------------------
I am agreeable to a just warning being issued and then passing the PDF as a
verified PDF/A.
I have only run across this error on PDF/As generated by a very non standard
method using Ghostscript 8.64.
I would not wish to change the PDFBox jar more than necessary.
